When shooting roll film B/W I find that if I shoot for the highs and develope normally then I get some pretty good negatives. I found I like delta 100 at 100

When shooting roll film I shoot the same combination you do. I really like how easy a combination it is. Try rating Delta 100 at 50 for one roll and shoot the same scene with anther roll at 100. Develope both normal. Contact them together so you can see the difference. You can do the same with a roll exposed at 200. This gives you one set of negs that are exposed with one extra stop of light the 50, one normal the 100, and one with less light the 200. See which makes a neg you like the most. Like I said I like it at 100. To each their own.
